    if (shim!=null) shim.style.display = "none";
}

//Creates a new shim for the menu
function createMenuShim(menu)
{
    if (menu==null) return null;

    var shim = document.createElement("<iframe scrolling='no' frameborder='0'"+
                                      "style='position:absolute; top:0px;"+
                                      "left:0px; display:none'></iframe>");
    shim.name = getShimId(menu);
    shim.id = getShimId(menu);
    //Unremark this line if you need your menus to be transparent for some reason
    //shim.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0)";

    if (menu.offsetParent==null || menu.offsetParent.id=="")
    {
        window.document.body.appendChild(shim);
    }
    else
    {
        menu.offsetParent.appendChild(shim);
    }

    return shim;
}

//Creates an id for the shim based on the menu id
function getShimId(menu)
{
    if (menu.id==null) return "__shim";
    return "__shim"+menu.id;

//Returns the shim for a specific menu
function getShim(menu)

    return document.getElementById(getShimId(menu));
}

2、添加好上述函数后，仍在该文件中查找到：
menuobj.thestyle.visibility="visible"
在其后增加一行：openShim(menuobj,vmenuobj)
继续查找到：
function ie_clearshadow()
{
for(var i=0;i<fo_shadows.length;i++)
{
  if (fo_shadows[i])
   fo_shadows[i].style.display="none"
}
  fo_shadows=new Array();
}
把其改为：
function ie_clearshadow()
{
for(var i=0;i<fo_shadows.length;i++)
{
  if (fo_shadows[i])
   fo_shadows[i].style.display="none"
}
closeShim(window.menuobj)
  fo_shadows=new Array();
}
